Answer: The upgrades from TMG 4.0, 4.0a, 4.0b and/or 4.0c to 4.0d (either Gold or Silver Editions) are provided for free by Wholly Genes Software at the Upgrade Center

If you wish to upgrade an earlier version of TMG (or from the Silver Edition to the Gold Edition) you need to purchase the upgrade from Wholly Genes Web Store.

For the free upgrades you must be sure to download the correct version of the upgrade. In order to determine which version you need, open TMG and click on "Help > About TMG" and there will appear on you screen the version of TMG that is presently installed on your computer. It will also state if you have the Gold or Silver edition.

After determining which version you have, select the upgrade for that version and download it into any folder on your computer that you desire, making a note of where it is located for future use.

After downloading you must install the upgrade into the same folder where the present version currently exists.

From the Windows Desktop, click on Start > Run select [browse], select the folder and file that was downloaded, click on [Open] and then on [OK].
